Quantitative chemical analysis of textiles a mixture of polyimide fibers and certain other fibers1 ScopeThis standard specifies the use of chemical methods to determine the content of polyimide fibers in the following two component mixtures after removal of non-fibrous materials. method. ---Polyimide fiber; and --- Certain protein fiber (wool, special animal hair fiber, silk, etc.), cellulose fiber (cotton, linen, viscose, etc.), polyacyl Amine fiber, polyacrylonitrile fiber, polyester fiber, polytetrafluoroethylene fiber and polyphenylene sulfide fiber. This standard applies to mixtures containing polyimide fibers.2 Normative referencesThe following documents are indispensable for the application of this document.

Mixtures of polyamide fibres with certain other fibres (formic acid method) GB/T 2910.11 Textiles - Quantitative chemical analysis - Part 11. Mixtures of cellulose fibres and polyester fibres3 PrincipleAfter qualitative identification of the sample, select appropriate reagents to dissolve and remove one of the components, collect the residue, wash, dry and weigh, then use The corrected mass is calculated as the mass percentage of polyimide fibers to certain other fibers. Note. See Appendix A for the qualitative identification test method.4 General rules of testingAnalytically pure reagents for testing, distilled water and instruments, sample preparation, test procedures, drying, cooling, weighing and analysis of samples and insoluble fibers The calculation of the results is carried out in accordance with the provisions of GB/T 2910.1. If the test method is different from the above provisions, the test results are Listed in the body test method. 5 Mixture of polyimide fiber with certain protein fibers (hypochlorite method) 5.1 Principle Dissolve protein fibers from a mixture of known dry mass with a hypochlorite solution, collect the residue, wash, dry and weigh Weight; the corrected mass is used to calculate the percentage of polyimide fiber in the dry mass of the mixture. From the difference, the quality of protein fiber is obtained. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 36976-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 36976-2018_English as soon as possible, and keep you informed of the progress.
